Enums and Utilities

---

TextAnchor

Defines 9 screen anchor positions for message placement.

Package: net.tysontheember.emberstextapi.immersivemessages.api

public enum TextAnchor {
    TOP_LEFT(0f, 0f),
    TOP_CENTER(0.5f, 0f),
    TOP_RIGHT(1f, 0f),

    MIDDLE_LEFT(0f, 0.5f),
    MIDDLE(0.5f, 0.5f),
    MIDDLE_RIGHT(1f, 0.5f),

    BOTTOM_LEFT(0f, 1f),
    BOTTOM_CENTER(0.5f, 1f),
    BOTTOM_RIGHT(1f, 1f);

    public final float xFactor;  // 0.0 = left edge, 1.0 = right edge
    public final float yFactor;  // 0.0 = top edge, 1.0 = bottom edge
}

Messages are automatically clamped to stay on screen, so edge anchors won't render text off-screen.

Used in:

• ImmersiveMessage.anchor(TextAnchor)
• <anchor value=...> markup tag

---

TextAlign

Defines horizontal text alignment within an anchored position.

Package: net.tysontheember.emberstextapi.immersivemessages.api

public enum TextAlign {
    LEFT(0f),
    CENTER(0.5f),
    RIGHT(1f);

    public final float xFactor;
}

Used in:

• ImmersiveMessage.align(TextAlign)
• <align value=...> markup tag

---

ObfuscateMode

Defines the direction in which characters are revealed or hidden during obfuscation animations.

Package: net.tysontheember.emberstextapi.immersivemessages.api

public enum ObfuscateMode {
    NONE,       // No directional animation
    LEFT,       // Reveal/hide left to right
    RIGHT,      // Reveal/hide right to left
    CENTER,     // Reveal/hide from center outward
    EDGES,      // Reveal/hide from both edges inward
    RANDOM      // Random reveal order
}

Used in:

• <obfuscate direction=...> markup tag
• ImmersiveMessage.obfuscate(ObfuscateMode, float)
• TextSpan.obfuscate(ObfuscateMode, float)

---

ImmersiveColor

A color class that supports an alpha channel, unlike Minecraft's TextColor (which is RGB-only).

Package: net.tysontheember.emberstextapi.immersivemessages.util

public class ImmersiveColor {
    /** Create from a packed ARGB integer (0xAARRGGBB). */
    public ImmersiveColor(int argb)

    public int getRGB()          // Packed RGB (no alpha)
    public int getARGB()         // Packed ARGB
    public float getAlpha()      // Alpha as float (0.0–1.0)
}

Color format: 0xAARRGGBB

• AA = Alpha (00 = transparent, FF = opaque)
• RR = Red, GG = Green, BB = Blue

Examples:

new ImmersiveColor(0x80000000)   // 50% opaque black
new ImmersiveColor(0xFFFF0000)   // Fully opaque red
new ImmersiveColor(0x4DFFFFFF)   // 30% opaque white

Used in:

• ImmersiveMessage.backgroundColors(ImmersiveColor, ImmersiveColor, ImmersiveColor)
• ImmersiveMessage.backgroundGradient(ImmersiveColor...)
• TextSpan.background(ImmersiveColor)
• TextSpan.globalBackgroundColor(ImmersiveColor)

ColorParser

Utility class for parsing color strings into various formats.

Package: net.tysontheember.emberstextapi.immersivemessages.util

public class ColorParser {

    /** Parse hex string to RGB float array [r, g, b]. Accepts "FF0000" or "#FF0000". */
    public static Optional<float[]> parseToRgbFloats(String hex)

    /** Packed RGB integer to float array [r, g, b]. */
    public static float[] intToRgbFloats(int packed)

    /** RGB float values to packed integer. */
    public static int rgbFloatsToInt(float r, float g, float b)

    /**
     * Parse a color string to ImmersiveColor.
     * Accepts hex strings with or without alpha channel.
     */
    public static ImmersiveColor parseImmersiveColor(String hex)
}

---

ViewStateTracker

Prevents typewriter and obfuscation animations from resetting when text is re-rendered (e.g., when a tooltip re-renders on hover).

Package: net.tysontheember.emberstextapi.util

Each message or text context gets a unique context ID. The tracker remembers whether an animation has started for that context, so re-rendering doesn't restart it.

Used internally by the rendering system. You generally don't need to interact with it directly unless implementing custom animation-based effects that need to survive re-renders.

---

TextureSizingMode

Defines how a texture background fills the available space.

Package: net.tysontheember.emberstextapi.immersivemessages.api (inner enum of ImmersiveMessage)

public enum TextureSizingMode {
    STRETCH,
    CROP
}

Value	Description
STRETCH	Stretches the texture to fill the background area exactly. May distort aspect ratio. (default)
CROP	Scales the texture to cover the background area while preserving aspect ratio. Excess is cropped.

Used in:

• ImmersiveMessage.textureBackgroundMode(TextureSizingMode)

String parsing: Also accepts "crop", "cut", or "cover" (all map to CROP). Anything else maps to STRETCH.

---

TextLayoutCache

Caches computed text layout calculations to avoid redundant work each frame.

Package: net.tysontheember.emberstextapi.client

• Automatically cleared when the GUI scale changes.
• Transparent to mod developers — it operates entirely internally during rendering.
• Significantly improves performance for messages that don't change content between frames.

You don't need to interact with this class directly.
